Audio output balancing
An example implementation involves a first playback device receiving audio content to be played back by the first playback device and a second playback device in synchrony. The audio content includes a first stereo component to be played by the first playback device and a second stereo component to be played by the second playback device. The first playback device determines a first limiting result that represents playback of the second stereo component by a second playback device by applying, to the second stereo component, a pre-determined volume-limiting function that is associated with the second playback device. The first playback device determines another volume-limiting function based on the first limiting result and applies the determined volume-limiting function to the first stereo component when playing the first stereo component in synchrony with the playback of the second stereo component by the second playback device.

FIELD OF THE DISCLOSUREThe disclosure is related to consumer goods and, more particularly, to methods, systems, products, features, services, and other elements directed to media playback or some aspect thereof.
BACKGROUNDOptions for accessing and listening to digital audio in an out-loud setting were severely limited until in 2003, when SONOS, Inc. filed for one of its first patent applications, entitled “Method for Synchronizing Audio Playback between Multiple Networked Devices,” and began offering a media playback system for sale in 2005. The Sonos Wireless HiFi System enables people to experience music from virtually unlimited sources via one or more networked playback devices. Through a software control application installed on a smartphone, tablet, or computer, one can play what he or she wants in any room that has a networked playback device. Additionally, using the controller, for example, different songs can be streamed to each room with a playback device, rooms can be grouped together for synchronous playback, or the same song can be heard in all rooms synchronously.
Given the ever growing interest in digital media, there continues to be a need to develop consumer-accessible technologies to further enhance the listening experience.
Features, aspects, and advantages of the presently disclosed technology may be better understood with regard to the following description, appended claims, and accompanying drawings where:
The drawings are for the purpose of illustrating example embodiments, but it is understood that the inventions are not limited to the arrangements and instrumentality shown in the drawings.
DETAILED DESCRIPTION I. OverviewEmbodiments described herein involve balancing of outputs from playback devices playing audio content in synchrony. The playback devices may be two or more playback devices of a media playback system that have been configured as a synchrony group (two or more playback devices configured to play audio content in synchrony), stereo paired playback devices, a consolidated player, or any combination thereof. Discussions of example media playback systems, example playback devices, and example configurations of playback devices of the media playback system may be found below in sections II.a.-II.d.
Typically, playback devices of the media system have acoustic limits. Acoustic limits of a playback device may be generally described as a maximum playback volume of the playback device before the acoustic output quality of the playback device begins to deteriorate. The acoustic limit of a playback device may vary over an audio playback frequency range of the playback device. In discussions herein, an acoustic limit of a playback device may also account for electric limits or other operational limits of the playback device. Accordingly, a limiter may be implemented on the playback device to attenuate input signals above a playback volume threshold such that the output of the playback device is capped at a certain volume level, thereby improving the acoustic output quality of the playback device. In one example, an amplifier gain control of the playback device may be implemented as the limiter. In such a case, a gain value of the playback device may be capped such that an input signal is not amplified beyond the playback volume threshold of the playback device. The limiter may be a dynamic limiter such that the gain value cap may be dynamically adjusted according to amplitudes of the input audio signal. Other example limiter implementations may also be possible.
In one example configuration for audio content playback, two playback devices may be configured as a stereo pair. In one case, the playback devices of a stereo pair may have different acoustic limits, and may therefore have different limiters implemented thereon. For instance, a left channel playback device of the stereo pair may have a higher playback volume threshold than a right channel playback device of the stereo pair. This may be, for example, because the left channel playback device and the right channel playback device have different audio amplifier and/or different transducer configurations and specifications. As a result of the different limiters, the output volume from the left channel playback device and the right channel playback device may become mismatched when a playback volume of the stereo pair is beyond the playback volume threshold one of the respective playback devices. In some cases, even if the left channel playback device and the right channel playback device have the same (or substantially the same) audio amplifier and transducer configurations and specifications (i.e. the playback devices are the same production model), and therefore having comparable acoustic limits and limiters implemented thereon, the left and right channel audio components of audio content to be rendered by the stereo pair may be sufficiently mismatched in volume such that one of the playback devices may still reach a limit before the other playback device.
In one example embodiment of the present application, the left channel playback device of the two stereo paired playback devices may be configured to receive both the left channel audio component and the right channel audio component. In one case, the left channel playback device may have access to the limiter for the right channel playback device. As such, the left channel playback device may apply the limiter for the right channel playback device to the right channel audio component. The left channel playback device may then determine a limiter based on a result of applying the right channel playback device limiter to the right channel audio component. In this case, the determined limiter may correlate to the acoustic limit of the right channel playback device. As such, the left channel playback device may apply the determined limiter when playing the left channel audio component while the right channel playback device renders the right channel audio component to achieve a balanced output from the stereo pair.
In another example audio content playback configuration, playback devices of a consolidated player may have different acoustic limits, and may therefore have different limiters implemented thereon. In one case, the consolidated player may include a mid-high frequency range playback device configured to render a mid-high frequency range audio component, and a low frequency range playback device (i.e. a subwoofer) configured to render a low frequency audio component. The mid-high frequency range audio component may have a first crossover frequency and the low frequency audio component may have a second crossover frequency. In some cases, the first and second crossover frequencies may be the same frequency.
In this example, the low frequency range playback device may have a higher acoustic limit than an acoustic limit of the mid-high frequency range playback device. Accordingly, the low frequency range playback device may have a playback volume threshold higher than that of the mid-high frequency range playback device. As a result of the different limiters, the low frequency output volume of the consolidated player and the mid-high frequency output volume of the consolidated player may become mismatched when the playback volume of the consolidated player is beyond the playback volume threshold of the mid-high frequency range playback device.
In one example embodiment of the present application, one or more of the playback devices of the consolidated player may receive a plurality of audio components, including audio components to be rendered by the playback device as well as audio components to be rendered by a different playback device. As one example, the low frequency range playback device may be configured to receive the low frequency audio component to be rendered by the low frequency range playback device as well as the mid-high frequency audio component to be rendered by the mid-high frequency range playback device. In one case, the low frequency range playback device may have access to the limiter for the mid-high frequency range playback device. As such, the low frequency range playback device may apply the limiter for the mid-high frequency range playback device to the mid-high frequency audio component to determine a first limiting result, and apply the limiter for the low frequency range playback device to the low frequency audio component to determine a second limiting result. In one example, determining the first limiting result may involve generating a model limited mid-high frequency audio signal by applying the limiter for the mid-high frequency range playback device to the mid-high frequency audio component. Similarly, determining the second limiting result may involve generating a model limited low frequency audio signal by applying the limiter for the low frequency range playback device to the low frequency audio component.
Based on the first and second limiting results, the low frequency range audio playback device may determine a limiter to apply to the low frequency audio component when rendering the low frequency audio component in synchrony with playback of the mid-high frequency audio component by the mid-high frequency range playback device as a consolidated player to achieve a balanced output across the audio frequency spectrum.
In another example embodiment, the acoustic limit of the mid-high frequency range playback device of a consolidated player may be lower towards the lower end of the mid-high frequency playback range than other playback frequency ranges of the mid-high frequency range playback device. In other words, the acoustic limit towards the lower end of the mid-high frequency playback range may become the limiting factor when applying the limiter of the mid-high frequency range playback device to the mid-high frequency audio component.
In such a scenario, if the low-frequency range playback device of the consolidated player is capable of playing frequencies in the lower end of the mid-high frequency playback range of the mid-high frequency range playback device at a higher acoustic limit, the crossover frequency for playing the low-frequency audio signal on the low-frequency range playback device may be shifted to a higher frequency. Also, the crossover frequency for playing the mid-high frequency audio signal on the mid-high frequency range playback device may also be shifted to a higher frequency. In other words, audio content within a frequency range towards the lower end of the mid-high frequency playback range may be played by the low frequency range playback device, rather than the mid-high frequency range playback device. Accordingly, in some cases, applying the limiter for the mid-high frequency range playback device to the modified mid-high frequency component may result in a less limited playback of the mid-high frequency audio component by the mid-high frequency range playback device, and the balanced output of the consolidated player may have a higher volume.
While the above example embodiments generally involve two playback devices as a either a stereo pair or consolidated player, one having ordinary in the art will appreciate that concepts within the example embodiments may be extended to any number of playback devices in a media playback system configured as any one or more of a synchrony group, stereo paired playback devices, or a consolidated player. In addition, while the above example embodiments describe certain grouped players (e.g., a left player in a stereo pair or a low frequency-range playback device in a consolidated player) performing various functions, it should be understood that other players in the group could perform these functions as well.
As indicated above, the present application involves balancing of outputs from playback devices playing audio content in synchrony. In one aspect, a first playback device is provided. The first playback device includes a processor, and memory having stored thereon instructions executable by the processor to cause the first playback device to perform functions. The functions include receiving a first audio signal. The first playback device is configured to play the first audio signal. The functions also include determining a first limiting result by applying to a second audio signal a limiting function associated with a second playback device, determining a limiting function based on the first limiting result, and configuring the first playback device to apply the determined limiting function when playing the first audio signal.
In another aspect, a method is provided. The method involves receiving, by a first playback device, a first audio signal and a second audio signal. The first playback device is configured to play the first audio signal in synchrony with a playback of the second audio signal by a second playback device. The method also involves determining a first limiting result by applying, by the first playback device, a first limiting function to the first audio signal. The first limiting function is associated with the first playback device. The method also involves determining a second limiting result by applying, by the first playback device, a second limiting function to the second audio signal. The second limiting function is associated with the second playback device. The method further involves determining a third limiting function based on the first limiting result and the second limiting result, and configuring the first playback device to apply the third limiting function when playing the first audio signal.
In yet another aspect, a non-transitory computer readable memory is provided. The non-transitory computer readable memory has stored thereon instructions executable by a computing device to cause the computing device to perform functions. The functions include receiving a first audio signal. The first playback device is configured to play the first audio signal. The functions also include determining a first limiting result by applying to a second audio signal a limiting function associated with a second playback device, determining a limiting function based on the first limiting result, and configuring the first playback device to apply the determined limiting function when playing the first audio signal.
It will be understood by one of ordinary skill in the art that this disclosure includes numerous other embodiments.
II. Example Operating EnvironmentFurther discussions relating to the different components of the example media playback system 100 and how the different components may interact to provide a user with a media experience may be found in the following sections. While discussions herein may generally refer to the example media playback system 100, technologies described herein are not limited to applications within, among other things, the home environment as shown in
a. Example Playback Devices
In one example, the processor 202 may be a clock-driven computing component configured to process input data according to instructions stored in the memory 206. The memory 206 may be a tangible computer-readable medium configured to store instructions executable by the processor 202. For instance, the memory 206 may be data storage that can be loaded with one or more of the software components 204 executable by the processor 202 to achieve certain functions. In one example, the functions may involve the playback device 200 retrieving audio data from an audio source or another playback device. In another example, the functions may involve the playback device 200 sending audio data to another device or playback device on a network. In yet another example, the functions may involve pairing of the playback device 200 with one or more playback devices to create a multi-channel audio environment.
Certain functions may involve the playback device 200 synchronizing playback of audio content with one or more other playback devices. During synchronous playback, a listener will preferably not be able to perceive time-delay differences between playback of the audio content by the playback device 200 and the one or more other playback devices. U.S. Pat. No. 8,234,395 entitled, “System and method for synchronizing operations among a plurality of independently clocked digital data processing devices,” which is hereby incorporated by reference, provides in more detail some examples for audio playback synchronization among playback devices.
The memory 206 may further be configured to store data associated with the playback device 200, such as one or more zones and/or zone groups the playback device 200 is a part of, audio sources accessible by the playback device 200, or a playback queue that the playback device 200 (or some other playback device) may be associated with. The data may be stored as one or more state variables that are periodically updated and used to describe the state of the playback device 200. The memory 206 may also include the data associated with the state of the other devices of the media system, and shared from time to time among the devices so that one or more of the devices have the most recent data associated with the system. Other embodiments are also possible.
The audio processing components 208 may include one or more digital-to-analog converters (DAC), an audio preprocessing component, an audio enhancement component or a digital signal processor (DSP), and so on. In one embodiment, one or more of the audio processing components 208 may be a subcomponent of the processor 202. In one example, audio content may be processed and/or intentionally altered by the audio processing components 208 to produce audio signals. The produced audio signals may then be provided to the audio amplifier(s) 210 for amplification and playback through speaker(s) 212. Particularly, the audio amplifier(s) 210 may include devices configured to amplify audio signals to a level for driving one or more of the speakers 212. The speaker(s) 212 may include an individual transducer (e.g., a “driver”) or a complete speaker system involving an enclosure with one or more drivers. A particular driver of the speaker(s) 212 may include, for example, a subwoofer (e.g., for low frequencies), a mid-range driver (e.g., for middle frequencies), and/or a tweeter (e.g., for high frequencies). In some cases, each transducer in the one or more speakers 212 may be driven by an individual corresponding audio amplifier of the audio amplifier(s) 210. In addition to producing analog signals for playback by the playback device 200, the audio processing components 208 may be configured to process audio content to be sent to one or more other playback devices for playback.
Audio content to be processed and/or played back by the playback device 200 may be received from an external source, such as via an audio line-in input connection (e.g., an auto-detecting 3.5 mm audio line-in connection) or the network interface 214.
The network interface 214 may be configured to facilitate a data flow between the playback device 200 and one or more other devices on a data network. As such, the playback device 200 may be configured to receive audio content over the data network from one or more other playback devices in communication with the playback device 200, network devices within a local area network, or audio content sources over a wide area network such as the Internet. In one example, the audio content and other signals transmitted and received by the playback device 200 may be transmitted in the form of digital packet data containing an Internet Protocol (IP)-based source address and IP-based destination addresses. In such a case, the network interface 214 may be configured to parse the digital packet data such that the data destined for the playback device 200 is properly received and processed by the playback device 200.
As shown, the network interface 214 may include wireless interface(s) 216 and wired interface(s) 218. The wireless interface(s) 216 may provide network interface functions for the playback device 200 to wirelessly communicate with other devices (e.g., other playback device(s), speaker(s), receiver(s), network device(s), control device(s) within a data network the playback device 200 is associated with) in accordance with a communication protocol (e.g., any wireless standard including IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4G mobile communication standard, and so on). The wired interface(s) 218 may provide network interface functions for the playback device 200 to communicate over a wired connection with other devices in accordance with a communication protocol (e.g., IEEE 802.3). While the network interface 214 shown in
In one example, the playback device 200 and one other playback device may be paired to play two separate audio components of audio content. For instance, playback device 200 may be configured to play a left channel audio component, while the other playback device may be configured to play a right channel audio component, thereby producing or enhancing a stereo effect of the audio content. The paired playback devices (also referred to as “bonded playback devices”) may further play audio content in synchrony with other playback devices.
In another example, the playback device 200 may be sonically consolidated with one or more other playback devices to form a single, consolidated playback device. A consolidated playback device may be configured to process and reproduce sound differently than an unconsolidated playback device or playback devices that are paired, because a consolidated playback device may have additional speaker drivers through which audio content may be rendered. For instance, if the playback device 200 is a playback device designed to render low frequency range audio content (i.e. a subwoofer), the playback device 200 may be consolidated with a playback device designed to render full frequency range audio content. In such a case, the full frequency range playback device, when consolidated with the low frequency playback device 200, may be configured to render only the mid and high frequency components of audio content, while the low frequency range playback device 200 renders the low frequency component of the audio content. The consolidated playback device may further be paired with a single playback device or yet another consolidated playback device.
By way of illustration, SONOS, Inc. presently offers (or has offered) for sale certain playback devices including a “PLAY:1,” “PLAY:3,” “PLAY:5,” “PLAYBAR,” “CONNECT:AMP,” “CONNECT,” and “SUB.” Any other past, present, and/or future playback devices may additionally or alternatively be used to implement the playback devices of example embodiments disclosed herein. Additionally, it is understood that a playback device is not limited to the example illustrated in
b. Example Playback Zone Configurations
Referring back to the media playback system 100 of
As shown in
In one example, one or more playback zones in the environment of
As suggested above, the zone configurations of the media playback system 100 may be dynamically modified, and in some embodiments, the media playback system 100 supports numerous configurations. For instance, if a user physically moves one or more playback devices to or from a zone, the media playback system 100 may be reconfigured to accommodate the change(s). For instance, if the user physically moves the playback device 102 from the balcony zone to the office zone, the office zone may now include both the playback device 118 and the playback device 102. The playback device 102 may be paired or grouped with the office zone and/or renamed if so desired via a control device such as the control devices 126 and 128. On the other hand, if the one or more playback devices are moved to a particular area in the home environment that is not already a playback zone, a new playback zone may be created for the particular area.
Further, different playback zones of the media playback system 100 may be dynamically combined into zone groups or split up into individual playback zones. For instance, the dining room zone and the kitchen zone 114 may be combined into a zone group for a dinner party such that playback devices 112 and 114 may render audio content in synchrony. On the other hand, the living room zone may be split into a television zone including playback device 104, and a listening zone including playback devices 106, 108, and 110, if the user wishes to listen to music in the living room space while another user wishes to watch television.
c. Example Control Devices
The processor 302 may be configured to perform functions relevant to facilitating user access, control, and configuration of the media playback system 100. The memory 304 may be configured to store instructions executable by the processor 302 to perform those functions. The memory 304 may also be configured to store the media playback system controller application software and other data associated with the media playback system 100 and the user.
In one example, the network interface 306 may be based on an industry standard (e.g., infrared, radio, wired standards including IEEE 802.3, wireless standards including IEEE 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.15, 4G mobile communication standard, and so on). The network interface 306 may provide a means for the control device 300 to communicate with other devices in the media playback system 100. In one example, data and information (e.g., such as a state variable) may be communicated between control device 300 and other devices via the network interface 306. For instance, playback zone and zone group configurations in the media playback system 100 may be received by the control device 300 from a playback device or another network device, or transmitted by the control device 300 to another playback device or network device via the network interface 306. In some cases, the other network device may be another control device.
Playback device control commands such as volume control and audio playback control may also be communicated from the control device 300 to a playback device via the network interface 306. As suggested above, changes to configurations of the media playback system 100 may also be performed by a user using the control device 300. The configuration changes may include adding/removing one or more playback devices to/from a zone, adding/removing one or more zones to/from a zone group, forming a bonded or consolidated player, separating one or more playback devices from a bonded or consolidated player, among others. Accordingly, the control device 300 may sometimes be referred to as a controller, whether the control device 300 is a dedicated controller or a network device on which media playback system controller application software is installed.
The user interface 308 of the control device 300 may be configured to facilitate user access and control of the media playback system 100, by providing a controller interface such as the controller interface 400 shown in
The playback control region 410 may include selectable (e.g., by way of touch or by using a cursor) icons to cause playback devices in a selected playback zone or zone group to play or pause, fast forward, rewind, skip to next, skip to previous, enter/exit shuffle mode, enter/exit repeat mode, enter/exit cross fade mode. The playback control region 410 may also include selectable icons to modify equalization settings, and playback volume, among other possibilities.
The playback zone region 420 may include representations of playback zones within the media playback system 100. In some embodiments, the graphical representations of playback zones may be selectable to bring up additional selectable icons to manage or configure the playback zones in the media playback system, such as a creation of bonded zones, creation of zone groups, separation of zone groups, and renaming of zone groups, among other possibilities.
For example, as shown, a “group” icon may be provided within each of the graphical representations of playback zones. The “group” icon provided within a graphical representation of a particular zone may be selectable to bring up options to select one or more other zones in the media playback system to be grouped with the particular zone. Once grouped, playback devices in the zones that have been grouped with the particular zone will be configured to play audio content in synchrony with the playback device(s) in the particular zone. Analogously, a “group” icon may be provided within a graphical representation of a zone group. In this case, the “group” icon may be selectable to bring up options to deselect one or more zones in the zone group to be removed from the zone group. Other interactions and implementations for grouping and ungrouping zones via a user interface such as the user interface 400 are also possible. The representations of playback zones in the playback zone region 420 may be dynamically updated as playback zone or zone group configurations are modified.
The playback status region 430 may include graphical representations of audio content that is presently being played, previously played, or scheduled to play next in the selected playback zone or zone group. The selected playback zone or zone group may be visually distinguished on the user interface, such as within the playback zone region 420 and/or the playback status region 430. The graphical representations may include track title, artist name, album name, album year, track length, and other relevant information that may be useful for the user to know when controlling the media playback system via the user interface 400.
The playback queue region 440 may include graphical representations of audio content in a playback queue associated with the selected playback zone or zone group. In some embodiments, each playback zone or zone group may be associated with a playback queue containing information corresponding to zero or more audio items for playback by the playback zone or zone group. For instance, each audio item in the playback queue may comprise a uniform resource identifier (URI), a uniform resource locator (URL) or some other identifier that may be used by a playback device in the playback zone or zone group to find and/or retrieve the audio item from a local audio content source or a networked audio content source, possibly for playback by the playback device.
In one example, a playlist may be added to a playback queue, in which case information corresponding to each audio item in the playlist may be added to the playback queue. In another example, audio items in a playback queue may be saved as a playlist. In a further example, a playback queue may be empty, or populated but “not in use” when the playback zone or zone group is playing continuously streaming audio content, such as Internet radio that may continue to play until otherwise stopped, rather than discrete audio items that have playback durations. In an alternative embodiment, a playback queue can include Internet radio and/or other streaming audio content items and be “in use” when the playback zone or zone group is playing those items. Other examples are also possible.
When playback zones or zone groups are “grouped” or “ungrouped,” playback queues associated with the affected playback zones or zone groups may be cleared or re-associated. For example, if a first playback zone including a first playback queue is grouped with a second playback zone including a second playback queue, the established zone group may have an associated playback queue that is initially empty, that contains audio items from the first playback queue (such as if the second playback zone was added to the first playback zone), that contains audio items from the second playback queue (such as if the first playback zone was added to the second playback zone), or a combination of audio items from both the first and second playback queues. Subsequently, if the established zone group is ungrouped, the resulting first playback zone may be re-associated with the previous first playback queue, or be associated with a new playback queue that is empty or contains audio items from the playback queue associated with the established zone group before the established zone group was ungrouped. Similarly, the resulting second playback zone may be re-associated with the previous second playback queue, or be associated with a new playback queue that is empty, or contains audio items from the playback queue associated with the established zone group before the established zone group was ungrouped. Other examples are also possible.
Referring back to the user interface 400 of
The audio content sources region 450 may include graphical representations of selectable audio content sources from which audio content may be retrieved and played by the selected playback zone or zone group. Discussions pertaining to audio content sources may be found in the following section.
d. Example Audio Content Sources
As indicated previously, one or more playback devices in a zone or zone group may be configured to retrieve for playback audio content (e.g. according to a corresponding URI or URL for the audio content) from a variety of available audio content sources. In one example, audio content may be retrieved by a playback device directly from a corresponding audio content source (e.g., a line-in connection). In another example, audio content may be provided to a playback device over a network via one or more other playback devices or network devices.
Example audio content sources may include a memory of one or more playback devices in a media playback system such as the media playback system 100 of
In some embodiments, audio content sources may be regularly added or removed from a media playback system such as the media playback system 100 of
The above discussions relating to playback devices, controller devices, playback zone configurations, and media content sources provide only some examples of operating environments within which functions and methods described below may be implemented. Other operating environments and configurations of media playback systems, playback devices, and network devices not explicitly described herein may also be applicable and suitable for implementation of the functions and methods.
III. Example Methods for Audio Output Balancing During Synchronized PlaybackAs discussed above, embodiments described herein may involve balancing of outputs from playback devices playing audio content in synchrony.
a. First Example Method for Audio Output Balancing During Synchronized Playback
In addition, for the method 500 and other processes and methods disclosed herein, the flowchart shows functionality and operation of one possible implementation of present embodiments. In this regard, each block may represent a module, a segment, or a portion of program code, which includes one or more instructions executable by a processor for implementing specific logical functions or steps in the process. The program code may be stored on any type of computer readable medium, for example, such as a storage device including a disk or hard drive. The computer readable medium may include non-transitory computer readable medium, for example, such as computer-readable media that stores data for short periods of time like register memory, processor cache and Random Access Memory (RAM). The computer readable medium may also include non-transitory media, such as secondary or persistent long term storage, like read only memory (ROM), optical or magnetic disks, compact-disc read only memory (CD-ROM), for example. The computer readable media may also be any other volatile or non-volatile storage systems. The computer readable medium may be considered a computer readable storage medium, for example, or a tangible storage device. In addition, for the method 500 and other processes and methods disclosed herein, each block in
At block 502, the method 500 involves receiving a first audio signal to be played by a first playback device. In one example, the first playback device may be configured to play the first audio signal in synchrony with the playback of a second audio signal by a second playback device.
In this case, the first and second playback devices may be configured as a consolidated player, and the audio signal 602 may be the first audio signal to be played by the first playback device while the audio signal 604 may be the second audio signal to be played by the second playback device. In such a case, the first playback device may be a playback device configured for playing low frequency audio content (i.e., a subwoofer), and the second playback device may be a playback device configured to play a full frequency range or mid-high frequency range of audio content. For purposes of illustration, the first and second playback devices may be playback devices 104 and 110, respectively, as shown in
In one case, the first playback device in the consolidated player or stereo pair may be a primary player configured to receive audio signals and send the audio signals to other playback devices within the consolidated player or stereo pair for playback. As such, in one example, the first audio signal and the second audio signal may be received by the first playback device. For instance, in connection with
Referring back to
The first playback device, in order to apply the limiting function associated with the second playback device, has access to the limiting function associated with the second playback device. In one example, the first playback device may receive the limiting function associated with the second playback device when the consolidated player or stereo pair is formed. In another example, the first playback device may receive the limiting function associated with the second playback device when either the first playback device or the second playback device joins the media playback system that the first and second playback devices are parts of. In one case, the limiting function associated with the second playback device may be provided to the first playback device by the second playback device. In another case, the limiting function associated with the second playback device may be provided from a local or remote network device or server.
In some instances, the limiting function associated with the second playback device may be specific to the particular second playback device. In other instances, the limiting function associated with the second playback device may be associated with a production model of the second playback device, such that all playback devices of that production model have the same limiting functions. In such instances, the first playback device may already have stored thereon a particular limiting function associated with the production model of the second playback device and may access the particular limiting function as the limiting function associated with the second playback device.
In some cases, the limiting function associated with the second playback device may be a modified version of the limiting function that the second playback device actually applies when playing audio content. For instance, the limiting function applied by the first playback device may be a simplified version of the limiting function applied by the second playback device when the second playback device is playing audio content to lessen the processing load of the first playback device when executing the block 504. Other examples of limiting functions and limiting function sources are also possible.
For purposes of illustration,
In some cases, the acoustic limit of a playback device may be lower (more limited) towards the lower frequencies of the playback frequency of the playback device. In other words, the ratio by which an audio signal is scaled when applying the limiting function associated with the playback device may be dependent primarily on the lower frequencies of the audio signal. In fact, in some instance, the limiting function may only be provided for lower frequency audio signal anyway. As such, the first playback device may in some embodiments, process the second audio signal such that only the lower frequencies of the second audio signal remain (i.e. using a low-pass filter). Continuing with the examples above, the first playback device may consequently apply the limiting function 650 associated with the second playback device to just the remaining lower frequencies of the second audio signal 606 to determine the first limiting result. In some cases, applying the limiting function 650 to only the lower frequencies of the second audio signal 606 may reduce the overall processing power and processing time of block 504.
For a balanced output between the playback of the first audio signal 608 by the first playback device and playback of the second audio signal 606 by the second playback device, the first audio signal 608 may need to be limited or proportionally scaled to match that of the limited second audio signal 606′ when played by the first playback device. Accordingly, at block 506, the method 500 involves determining a limiting function based on the first limiting result.
At block 508, the method 500 involves configuring the first playback device to apply the determined limiting function when playing the first audio signal. Referring to
In one example, as suggested previously, the first playback device may be a primary playback device in the stereo pair and as such may also be configured to cause and/or coordinate the second playback device to play the second audio signal 606 in synchrony with the playback of the first audio signal 608. In some embodiments, synchronous playback between the first and second playback devices may be performed as described in previously referenced U.S. Pat. No. 8,234,395, also assigned to SONOS, Inc.
As a primary player, the first playback device may be configured to send the second audio signal 606 to the second playback device for the second playback device to play in synchrony with the playback of the first audio signal 608 by the first playback device (while applying the determined limiting function 660). In some embodiments, if the first playback device generated the limited second audio signal 606′ when applying the limiting function 650 to the second audio signal 606 to determine the first limiting result in block 504, the first playback device may send the limited second audio signal 606′ to the second playback device for the second playback device to render, thereby eliminating the need for the second playback device to apply the limiting function 650 associated with the second device when playing the second audio signal 606. In other embodiments, the first playback device may simply send the audio signal 606 to the second playback device, and the playback device may apply its limiting function 650 to the audio signal 606.
While discussions above relating to the method 500 are generally directed to the balancing of audio output during synchronized playback by a stereo pair, one having ordinary skill in the art will appreciate that method 500 may be applied to other synchronized playback scenarios as well. Further, note that in some embodiments, the illustrative examples discussed in connection to the method 500 and
b. Second Example Method for Audio Output Balancing During Synchronized Playback
In the example discussed above in connection to
At block 702, the method 700 involves receiving, by a first playback device, a first audio signal and a second audio signal. In one example, as discussed above in connection to the method 500, the first playback device may be configured to play the first audio signal in synchrony with the playback of the second audio signal by a second playback device. Accordingly, in one example, the first and second audio signals may be the audio signals 602 and 604, respectively shown and discussed in connection to
At block 704, the method 700 involves the first playback device determining a first limiting result by applying a first limiting function to the first audio signal. In this case, the first limiting function may be one that is associated with the first playback device, and may represent an acoustic limit of the first playback device.
In this example, as shown in
At block 706, the method 700 involves the first playback device determining a second limiting result by applying a second limiting function to the second audio signal. The second limiting function in this example may be associated with the second playback device. As such, block 706 may be similar to block 504 of the method 500, and any discussions above in connection to block 504 may apply to block 706 as well. For instance, the first playback device may be configured to receive the second limiting function prior to determining the second limiting result.
In this example, as shown in
At block 708, the method 700 involves the first playback device determining a third limiting function based on the first limiting result and the second limiting result. Similar to that discussed in connection to block 506 of the method 500, one of the first and second audio signals may be limited or proportionally scaled to match the limited result of the other for a balanced output between the playback of the first and second audio signals.
At block 710, the method 700 involves configuring the first playback device to apply the third limiting function when playing the first audio signal. Referring to
Synchronous playback of the first audio signal 802 with playback of the second audio signal 604 by the second playback device may be similar to the synchronous playback of the first audio signal 608 by the first playback device and the second audio signal 606 by the second playback device discussed previously in connection to the method 500 of
c. Third Example Method for Audio Output Balancing During Synchronized Playback
In the illustrative examples discussed above in connection to
At block 902, the method 900 involves receiving a first audio signal to be played by a first playback device according to a first crossover frequency, and a second audio signal to be played by a second playback device according to a second crossover frequency. Continuing with the examples above, the first audio signal may be the audio signal 602 shown in
In some embodiments, the first audio signal 602 and the second audio signal 604 may be received individually, while in some other embodiments, audio content including both the first audio signal 602 and the second audio signal 604 may be received as a whole, and band-pass filters may be applied to the received audio content to generate the first audio signal 602 and the second audio signal 604. In some cases, the first and second crossover frequencies (in this example, both may be the crossover frequency 610) may be received along with the audio content to generate and apply applicable band-pass filters. In some other cases, the first and second crossover frequencies may be predetermined when the first and second playback devices were configured as a consolidated player based on playback capabilities and configurations of the first and second playback devices. Block 902 may be similar to block 702 discussed above in connection to
At block 904, the method 900 involves determining a first limiting result by applying a first limiting function to the first audio signal, and at block 906, the method 900 involves determining a second limiting result by applying a second limiting function to the second audio signal. Similar to blocks 704 and 706, respectively, and continuing with the above examples, the first limiting function may be the limiting function 850 that is associated with the first playback device, and the second limiting function may be the limiting function 860 that is associated with the second playback device, shown previously in
At block 908, the method 900 involves configuring the first playback device to play the first audio signal according to a third crossover frequency. Configuring the first playback device to play the first audio signal according to the third crossover frequency may involve first determining the third crossover frequency. In one example, the third crossover frequency may be determined based on the first limiting result and the second limiting result. For instance, the third crossover frequency may be determined based on frequencies at which the second playback device is limited, and determining whether the first playback device is capable of playing audio content in those frequencies. In the example shown in
In one example, the first playback device may be configured to send to the second playback device, data indicating the third crossover frequency, and configuring, or causing the second playback device to be configured to play the second audio signal according to the fourth crossover frequency. In this case, the second playback device may be configured to determine the fourth crossover frequency based on the third crossover frequency. In the case the second playback device receives the audio content including both the first audio signal 602 and the second audio signal 604, the second playback device may be configured to apply band-pass filters according to the fourth crossover frequency to generate the second audio signal 1004 to be played by the second playback device. As indicated previously, the fourth crossover frequency may in some cases be the same as the third crossover frequency 1010 of 150 Hz.
In another example, the first playback device may be configured to determine the fourth crossover frequency based on the third crossover frequency, and send to the second playback device, data indicating the fourth crossover frequency. In this case the second playback device may be configured to apply band-pass filters according to the fourth crossover frequency 1010 to generate the second audio signal 1004 to be played without having to determine the fourth crossover frequency itself.
Playback of the first audio signal 1002 by the first playback device in synchrony with playback of the second audio signal 1004 by the second playback device may result in a more balanced output than playback of the first audio signal 602 by the first playback device in synchrony with playback of the second audio signal 604 by the second playback device. In some embodiments, the dynamic adjustment of crossover frequencies may result in sufficient audio output balancing during synchronized playback. In some other embodiments, however, additional steps, such as those described in connection to
As shown in
As indicated previously, one of the first audio signal 1002 and second audio signal 1004 may need to be limited or proportionally scaled to match the limited result of the other for a balanced output between the playback of the first audio signal 1002 by the first playback device and playback of the second audio signal 1004 by the second playback device. Comparing n/(m+n) and q/(p+q) as shown in
Accordingly, as shown in
The first playback device may accordingly be configured to apply the limiting function 1070 when playing the first audio signal 1002. As shown, a limited first audio signal 1012′ generated when applying the limiting function 1070 to the first audio signal 1002 is proportionally scaled down from the first audio signal 1002 by the ratio of y/(x+y). As indicated previously, applying the limiting function 1070 to the first audio signal 1002 may involve adjusting an amplifier gain applied to the first audio signal 1002 by the first playback device. As shown in
When compared to the limited first and second audio signals 812′ and 804′ shown in
While discussions above relating to the method 900 are generally directed to the balancing of audio output during synchronized playback by a consolidated player, one having ordinary skill in the art will appreciate that method 900 may be applied to other synchronized playback scenarios as well.
